I saw this movie for the first time in Chicago, in the winter of 1980. It impressed me a lot, and its images lingered on my mind for a long time. I saw it again 12 years later and still found it a good movie, despite its violent sexual issues. I've revisited it once again a few days ago in a wonderful DVD version and I was deeply impressed. This is one of those movies similar to wine: as time goes by, it gets older...and better. No doubt about it, it's quite crude and may shock a large number of viewers. The incest theme can only be compared to the treatment that Louis Malle had previously given to the subject in "Le Soufle Au Coeur" in 1971 (again, the relation between a mother and her teenager son). However, two aspects make me prefer this film rather than the excellent Malle movie: Jill Clayburg'interpretation and the wonderful operatic background that Bertolucci gave to his drama. Besides- and this is no novelty coming from Bertolucci - it's such a beautiful movie form the visual viewpoint: wonderfully shot, edited and with a fascinanting tempo that allows you to enjoy every second of it. If you haven't seen this movie, don't hesitate in getting it: you might get disturbed, it will probably shock you, but be sure that you'll see cinematographic images as you've never seen before.
